EXG™ 4-Electrode Wearable ECG — EMS-Optimized Rate & Rhythm Monitoring

EMS-optimized ECG for rate and rhythm monitoring

The EXG™ 4-Electrode Wearable ECG — also referred to as the 4-Lead — is designed with EMS crews in mind. It's the EMS-optimized 4-Electrode configuration of the EXG™ platform, built for rate and rhythm monitoring on lower-acuity patients where full diagnostic 12-Lead information may not be required, and where fast, flexible electrode placement matters more than lead count.

Now available through Heart Medical for U.S. EMS agencies.

Why the 4-Electrode configuration matters for EMS

Prehospital cardiac assessment isn't always about STEMI transport. A large share of EMS runs involve stable patients who need rate and rhythm monitoring rather than full diagnostic ECG — post-syncope workups, medication assessments, complaints of palpitations, and countless other lower-acuity encounters where a fast, defensible tracing is what the crew actually needs.

The EXG™ 4-Electrode (4-Lead) is optimized for exactly those situations:

• Rapid deployment — single connection enables setup in under 60 seconds
• Multiple placement options — wrist-to-wrist, limb-to-limb, or limb-to-torso configurations for whatever the patient position allows
• Single-cable design — one universal adapter compatible with all portable ECG monitors; same adapter as the EXG™ 12-Lead flagship

For high-acuity STEMI transport, EMS agencies typically carry the EXG™ 12-Lead flagship alongside this 4-Electrode — 12-Lead for STEMI workup, 4-Electrode (4-Lead) for the majority of everyday runs.

Key features — 4-Electrode (4-Lead) configuration

• Rapid deployment — single connection enables setup in under 60 seconds; one universal adapter compatible with all portable ECG monitors
• Rate and rhythm monitoring for lower-acuity patients
• Multiple placement configurations:
  • Wrist-to-wrist
  • Limb-to-limb
  • Limb-to-torso
• Motion artifact reduction — improved methods for high-activity environments
• Single-cable design — uses the same adapter as EXG™ 12-Lead continuous wearable patch
• Disposable, per-patient — single-use consumable
• Universal compatibility — one cable fits any standard ECG monitor; works with LP15, X Series, and other EMS ECG monitors

Intended use

The EXG™ 4-Electrode (4-Lead) is intended for assessing lower-acuity patients where you may not require full diagnostic information. For diagnostic 12-Lead ECG in STEMI transport or hospital cardiology workflows, use the EXG™ 12-Lead flagship instead.

Clinical applications

• EMS low-acuity encounters — post-syncope, palpitations, medication assessments, general rate & rhythm documentation
• Field triage where full 12-lead may not be needed
• Interfacility transports for stable patients
• Non-STEMI cardiac complaint workups on scene or during transport
• Any prehospital situation where fast electrode placement and multiple placement options matter more than lead count

Purchase and configuration workflow

1. Request a scoped quote. Share your agency's monthly EMS run volume, station count, and existing ECG monitor infrastructure.
2. Configuration walkthrough. Most EMS agencies carry both 4-Lead (for low-acuity) and 12-Lead (for STEMI transport). Confirm the volume mix.
3. Deployment planning. Coordinate with your biomed / clinical engineering team on integration and applications training.
4. Standing-order supply. EXG™ 4-Lead is disposable per-patient — predictable EMS run volumes fit well with standing-order setup.
